A radiation detector includes a printed circuit board and a detector assembly operably connected to the printed circuit board. The detector assembly includes a silicon photomultiplier and an organic scintillator coating applied to a surface of the silicon photomultiplier. A reflective foil covers the organic scintillator coating. A light sealing cover is secured to the printed circuit board such that the silicon photomultiplier and the organic scintillator are encapsulated within the light sealing cover.

An object of the present invention is to enable a scintillator panel of a type having a barrier rib to have sufficient mechanical strength and enhanced brightness. A scintillator panel including a substrate, a barrier rib formed on the substrate, and a scintillator layer having a phosphor and sectioned by the barrier rib, wherein the barrier rib contains one or more compounds (P) selected from the group consisting of polyimides, polyamides, polyamideimides, and polybenzoxazoles.

A device having: a scintillator material, an optically transparent element containing a glass or polymer and gadolinium oxide, and one or more photomultiplier tubes adjacent to the scintillator material. The optically transparent element is surrounded by the scintillator material.

Embodiments relate to an advanced fast and thermal neutron detector material composition with the properties useful for Special Nuclear Material (SNM) detection. Specific embodiments of the material composition result in two excimer scintillation light production mechanisms that provide two corresponding independent techniques for gamma discrimination; namely Pulse Shape Discrimination and Pulse Height Discrimination. A dual discrimination method, Pulse Shape and Pulse Height Discrimination (PSHD), can be implemented relying on both pulse height discrimination and pulse shape discrimination, and can allow the operation of large area, fast and thermal neutron detectors.

Provided is a scintillator that includes: first phosphors each including an inorganic fluorescent compound; and a second phosphor including a fluorescent resin.
